Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional hardware components are implemented to duplicate hardware paths for video correctness checking, then video correctness checking capability is improved, but hardware costs and component sizes increase

Engineering Contradiction:

Improvevideo correctness checking capabilityVSAvoidhardware component size

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the video correctness checking function with the existing video processing hardware pipeline. Instead of duplicating hardware paths, the system uses the same hardware resources to perform both the primary video processing task and the correctness checking comparison, thereby avoiding increased hardware component size while maintaining video correctness checking capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hardware pipeline is designed to perform multiple functions: it processes video frames for the primary purpose while simultaneously performing correctness checking by comparing against reference frames. This multi-functionality allows the same hardware components to serve both video processing and error detection without requiring additional dedicated hardware

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If additional data flow processing is implemented to perform comparisons multiple times, then video correctness checking capability is improved, but system performance degrades (processing time, heat generation, power requirements)

Engineering Contradiction:

Improvevideo correctness checking capabilityVSAvoidsystem processing performance

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs correctness checking comparisons during the same processing cycle as the original video frame generation, rather than performing separate post-processing comparisons. By incorporating the comparison operation into the existing data flow path at the point of frame generation, the system avoids additional sequential processing steps that would degrade performance

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The hardware pipeline maintains continuous operation by performing correctness checking within the same processing cycle as the original video processing. The comparison operations are executed in parallel with the frame generation and processing operations, ensuring that no additional processing time is added to the overall system throughput

Inventive Principle:

Principle #20Continuity of useful action

AI summary

An apparatus comprising an interface and a processor. The interface may be configured to receive pixel data from a capture device. The processor may be configured to process the pixel data arranged as video frames, generate similar images from the video frames, perform preprocessing on the video frames and the similar images, perform a similarity check between the video frames and the similar images and determine an image correctness in response to the similarity check. The preprocessing of the video frames and the similar images may use a same hardware pipeline. The video frames may be discarded if the image correctness is below a threshold value.
